Catfish Info on Grayson Lake?

Does anybody catfish Grayson Lake on here? About everybody I know bass fishes it. Not trying to get anyone's spots, just wanting a general idea where to look for cats in there. We went last week and fished several spots but just couldn't find them. The lake also raised about 5-6' in 3 days, I think that was part of the reason we didn't do any good.
Any info is greatly appreciated!!!:cool2:
